In the FIGURES, which are not drawn to scale, like numerals refer to like features throughout the description. The following description is not to be taken in a limiting sense but is made merely for describing the general principles of the invention.

DETAILED DESCRIPTION

The following detailed description, taken in conjunction with the accompanying drawings, is merely exemplary in nature and is not intended to limit the described implementations or the application and uses of the described implementations. Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations.

For example, although the specific implementations described herein involve the retaining of a pipe escutcheon plate, implementations also may be applicable to other industries or applications wherein a retaining ring may a component to keep items in place securely.

FIG. 1 is an illustration of the prior art and the problem faced by many consumers today. FIG. 1 illustrates a loose escutcheon plate 100 installed without a retaining ring. In one example, when an end-user installs showerhead 110 using escutcheon plate 100, the consumer assumes that escutcheon plate 100 will maintain its secure position for a long duration without the necessity of adding any additional securing mechanism to hold the plate in place. However, as many end-users can attest to, pipe escutcheon plate 100 invariably becomes loose.

FIG. 2 is an illustration of a pipe escutcheon plate 100 with a retaining ring 200. In one example, when an end-user installs pipe escutcheon plate 100 along with retaining ring 200, the consumer can be more confident that retaining ring 200 will act as a securing mechanism to maintain pipe escutcheon plate 100 in position for a long duration. No additional adhesive, or locking mechanisms, need to be used for retaining ring 200 to work in an effective manner to hold pipe escutcheon plate 100 in place. Retaining ring 200 may be, for example, full-circular, non-detachable ring 300 as shown in FIG. 3 or it may be a detachable ring allowing for the end-user to install and uninstall as needed as shown in FIGS. 4A-4C, 5A-5C, 6A-6B, 7A-B, and 8A-C.

FIG. 3 is an illustration of non-detachable escutcheon plate retaining ring 300. In one example, non-detachable escutcheon plate retaining ring 300 may be a rounded circular ring having a diameter suitable to fit around standard plumbing pipe fixtures with a flat interior surface configured to grip the exterior of the pipe fixture for which it will be attached thereto. Alternatively, non-detachable escutcheon plate retaining ring 300 may be a round circular ring having a diameter suitable to fit around a standard plumbing pipe fixture with a concave interior surface to allow for suction (much like a suction cup) for gripping the exterior of the pipe fixture. Moreover, it is contemplated that exterior surface area 310 of retaining ring 300 may be of any design or configuration. Similarly, thickness 320 of retaining ring 300 may be of any suitable configuration, which may be of sufficient strength and elasticity to allow for the retention and security of an item within a removably fixed position. In general, the chemical composition of the fastener, such as a T-joint fastener, may be an elastomer, including silicone, and flexible plastic materials, or other suitable materials generally available and known in the art. Alternatively, the fastener can be fabricated from a flexible metal.

FIG. 4A is an illustration of retaining ring 400 showing male end fastener element 440 having a fastener, such as T-joint fastener 425 (FIG. 4C). In one implementation, retaining ring 400 is comprised of middle portion 430 and fastener elements 440, 450 on opposite ends of middle portion 430. Middle portion 430 may be of differing thicknesses or differing exterior design or both. Fastener elements 440, 450 on opposite ends of middle portion 430 respectively may include T-joint male fastener element 440, having T-joint male fastener protrusion 445, and a T-joint female fastener element 450, having female fastener element slot 455 configured to snugly receive male fastener protrusion 445. In one exemplary implementation, fastener elements 440, 450 can respectively include male end fastener element 440, which has a T-shaped protrusion 445, and female end fastener element 450, which has a T-shaped slot 455. Slot 455 can be preconfigured to allow for male end T-shaped protrusion 445 to snugly fit in. In one example, the end user may wrap the detachable retaining ring 400 around a pipe (not shown), engage T-shaped male end protrusion 445 with the T-shaped female end slot 455 to allow for retaining ring 400 to be installed properly. In the same way, the end user may want to detach retaining ring 400 and can easily do so by quickly and effectively disengaging T-joint male end protrusion 445 from T-joint female end slot 455.

Interior surface area 460 of detachable ring 400 may be a generally flat surface, with or without adhesive, to allow for better gripping around external components. Also, it is contemplated that the interior surface area 460 of detachable ring 400 may be a concave surface, like a suction cup, with or without adhesive, to allow for better gripping around external components. Moreover, the T-joint male end 445 may be aligned vertically along the top, exterior portion, along the middle portion, or along the bottom, interior portion of one end of the detachable retaining ring. T-joint fastener 425 instead may be a Y-joint fastener (See FIG. 7A-C and FIG. 8A-C).

FIG. 4B is an illustration of detachable escutcheon plate retaining ring 400 showing T-joint female end 455, which may be a slot, disposed to accept a T-joint male end protrusion 445, which may be a tab. In one example, T-joint female end slot 455 of detachable retaining ring 400 may be fitted to receive T-joint male end protrusion 445 in proper alignment. For example, if T-joint male end protrusion 445 is configured along exterior 475 of retaining ring 400, then T-joint female end slot 455 can be aligned closer to exterior 475 to create a flush finish once engaged. In another example, if T-joint male end protrusion 445 is configured along middle portion 430 of retaining ring 400, then T-joint female end slot 455 can have a deeper fitting to properly engage T-joint ends 445, 455 and create a flush finish. In yet another example, if T-joint male end protrusion 445 is configured along the lower portion of retaining ring 400, then T-joint female end slot 455 can be deeper or configured to have the opening along the interior portions of the ring to allow for a flush finish once engaged.

FIG. 4C is an illustration of the detachable escutcheon plate retaining ring 400 shown while T-joint fastener 425 is connected. In one example, detachable retaining ring 400 will form a circular seal around an exterior item, wherein retaining ring 400 can be detachable by the end user by disengaging T-joint fastener 425 employed by retaining ring 400. Also, the alignment of T-joint fastener 425 may be along the top (exterior portion), the middle (center portion), or along the bottom (interior) portion without departing from the functionality of the invention, which is to allow for the ring to fasten along opposite ends.

FIG. 5A is an illustration of detachable pipe escutcheon plate retaining ring 500 having a post clip fastener showing male end fastener element 530 having protruding tongue (tab) 535. In one implementation, retaining ring 500 is comprised of middle portion 525 and end fastener elements 530, 540 on opposite ends of middle portion 525. In such a configuration, middle portion 525 may be of differing thickness or exterior design. End fastener elements 530, 540 on opposite ends of middle portion 525 respectively include male end fastener element 530 having protruding tongue 535, and female end fastener element 540 having fastener element slot 545, which can be configured to receive protruding tongue 535. In some embodiments, protruding tongue 535 can include thereon locking post 550. Similarly, female end fastener slot 545 can include receiving cavity 555, which may be configured to lockingly receive locking post 550. In one example, the end user may wrap detachable retaining ring 500 around a pipe, engage protruding tongue 535, of male end fastener element 530, with female fastener end slot 545, of female fastener element 540, to allow for retaining ring 500 pipe to be installed properly. In some embodiments, locking post 550 can be pressed into receiving cavity 555 such that a secure fit of retaining ring 500 around the pipe (not shown) may be achieved. In a similar way, the end user may want to detach retaining ring 500 and can easily do so by disengaging male end protruding tongue 535 from female fastener end slot 545 very quickly and effectively. Similarly, locking post 550 can easily be removed from receiving cavity 555. It is contemplated that interior surface area 560 of detachable ring 500 may be a generally flat surface (FIG. 6A), with or without adhesive, to allow for better gripping around external components. Also, it is contemplated that interior surface area 560 of detachable ring 500 may be a generally concave surface (FIG. 6B), like a suction cup, with or without adhesive, to allow for better gripping around external components. Moreover, post clip male end fastener element 530 may be aligned vertically along the top (exterior portion), along the middle, or along the bottom (interior portion) as shown in FIG. 5A of one end of detachable retaining ring 500.

FIG. 5B is an illustration of the detachable escutcheon plate retaining ring 500 showing female end fastener element 540, which receives post clip male end fastener element 530. In one example, female end fastener element 540 of detachable retaining ring 500 may be configured to receive male end fastener element 530 in proper alignment. So, for example, if post clip male end fastener element 530 is configured along exterior surface 570 of retaining ring 500, then female end fastener element 540 may be aligned closer to exterior surface 570 to properly align to create a flush finish once engaged. In another example, if post clip male end protruding tongue 535 is configured along middle portion 525 of retaining ring 500, then female fastener end slot 545 will need to be configured along middle portion 525 to properly engage and create a flush finish once fastener ends 530, 540 are engaged. In yet another example, if post clip male end fastener element 530 is configured along the lower portion of retaining ring 500 as shown in FIG. 5A, then female end fastener element 540 can be configured to have the opening along interior surface area 560 of retaining ring 500 to allow for a flush finish once engaged as shown in FIG. 5B.

FIG. 5C is an illustration of detachable escutcheon plate retaining ring 500 shown while post clip male end protruding tongue 535 is coupled to female end slot 545. Similarly, locking post 550 can be pressed into receiving cavity 555. In one example, detachable retaining ring 500 may form a circular seal around an exterior item, wherein retaining ring 500 can be detached by the end user by disengaging end fastener elements 530, 540 employed by retaining ring 500. Also, the alignment of end fastener elements 530, 540 may be along the top (exterior portion), the middle (center portion), or along the bottom (interior) portion such that retaining ring 500 can fasten along opposite ends. FIG. 5C illustrates the post clip end fastener elements 530, 540 configured along interior surface area 560 of retaining ring 500 and creating a flush and secure seal.
